Application filed January 20, 1908. Serial No. 411,554.l

To all whom it may concern:

Be it known that I, JOHN PEARsoN, a citizen of the United States, lresiding at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Roofs,lof which the following is aspecication, reference being had therein to the accompanying drawing.

My invention relates to an improved carroof and the invention consists in the novel constructions, combinations and arrangements of parts hereinafter described and then particularly pointed out in the append? ed claims.

In the accompanying drawing in which like reference numerals indicate like parts `in the several figures; Figure 1 is a cross-sectional view of a car with the lower 'part broken away having a roof embodying iny invention; Fig. 2 is a detail longitudinal vertical sectional View on the line 2-42 of Fig. 1; Fig. 3 is a plan view of one side of the car roof with parts broken away showing the filler-strip; Fig. 4 is a detail longitudinal horizontal sectional View on the line 4- 4 of Fig. 1; Fig. 5 is a View similar to Fig. 2 with the parts separated for. the purpose of better illustration. Fig. 6 is a view in side elevation of my improved fastener. illustrating the manner of assembling the sheets and filler-strip with the fastener, parts being broken away; and Fig. 7 is a front view of the fastener.

In the drawing 10 indicates the carlines, 11 the purlins, 12 lthe ridge-purlin, 13 the sideplates, and 14 the sidings of the car, all of said parts being of the ordinary construction. The sheets 15 composing the roof are preferably made of galvanized iron, though it is of course to be understood that they may be made of any suitable material, and are provided with a series of corrugations extending the length of 'each sheet and comprising the upper and lower corrugations 16. The sheets r panels are somewhat greater in length than the width of the car, and are split or slitted along the crown or apex of the'corrugations 16, `as shown at 17,

a suitable distanceto form wings 19 which' may be turned down and secured to the sideplates so as to cover the ends of the channels formed by the corrugations. The wings formed by each slit or cut overlap by reason of the vexcess of metal embodying the corrugations, and when bolts or other similar fastenings are employed they may be passed throu h the overlapping parts of the wings in orer to co-act with the double thickness of metal thereby formed. The panels or sheets are made of any preferred widths and of sufficient length to extend across the entire width of the car and be secured to the plates in any suitable manner. In assembling the sheets each succeeding sheet overlaps the next preceding sheet a suitable distance to form an overlapping joint, and as shown in Figs. 2 and 5 this distance is substantially the width of two corrugations, the corrugations 16 of the overlapping sheet tting over similar corrugations of the under sheet.-

A. filler-strip 20 preferably of sheet` metal extends the length of the car and is provided at its rear with raised portions 21 which may be formed in any preferred manner, it being obvious that when the filler iS made of metal it mani7 be slitted as at 22 to allow the portions 21 to be suitably formed or struck up as corrugations in the metal. The front of the strip is bent downward at 23 to conform to the edge of the side plate' The corrugations 21 are of substantially the same width, height and curve as the corrugations 16 and are adapted to fill the channel formed by the corrugations to close the same in a manner to be made plain. It is to be understood that the filler-strip is a narrow strip which extends along the edge of the roof but a short distance across the top of the caras shown in Fig. 1.

In constructing a roof embodying my in- .vention the filler-strips are first placed in position along the edges of the car over the side-plates and upon them are then positioned the panels or sheets 15, each succeeding panel overlapping substantially two corrugations of the next preceding one, or a sufficient number to form a suitable joint, as hereinbefore described, the corrugations 21 of the filler-strips occupying the channels or4 grooves formed in the sheets 15 by the corrugations 16 and forming a filler or closure for the same. The wings 19 overlap the bent ends 23 of the filler-strips and are secured to the plates 13 in any suitable man-4 ner, as by nails 24 as shown in Fig. 1, the

portions 19 and 23 having suitable holes 25.

to receive the nails, though I preferably employ for this purpose a fastener such as shown in Figs. 6 and 7. This fastener is substantially Y-shaped comprising a flat body 26, preferably of malleable iron though any suitable material may be used, having the side-plate, a corrugated metallic filleran angularly disposed arm 27 which is provided with an opening 28 to receive a pin 29 made integral with the body or secured thereto in any suitable manner.

. is adapted to be attached to the side of the car in any desired manner, as by nails 30. When such a fastener is used the body of each fastener is so positioned that when the filler-strips and panels are assembled the pins 29 pass through the holes 25 the arms 27 are then bent inwardly toward the pins 29 which also passinto the openings 25.

'The holes 28 are of suicient size to permit the pins to pass loosely therethrough to allow the filler-strips and sheets to pivot thereon and thus provide elasticity for any movement of the sheets and filler-strips which may be due t0 the action of the car when in motion, thereby materially reducing the straining effect upon the roof.

In a car roof thus constructed and embodying my invention the raised portions 21 of the filler-strips serve to close the channels in the panels formed by the corrugations 16 and thus lprevent water or other foreign tically obviated as any water, etc., which may pass the wings 19 will be arrested by the filler-strip and run out between the strip and panel.- By fplroviding the panels with wings and the ler-strip with the down- .Wardly bent ede 23 I am able to secure both parts to t e side-plates by the same fastening.

Having described my invention I claim:

1. In a car roof, a side-plate, a series of i channeled metallic sheets depending over The body strip adapted to close thev channels in lthe sheets and having its front edge depending over the side-plate, and means to secure the depending edges of the sheets and fillerstrip to the side-plate.

2. In a car-roof, a series of channeled sheets or panels, a side-plate, and a corrugated filler-strip between the plate and panels, the corrugations of the strip closing the channels of the sheets, the edges of the sheets and strips being bent over and secured upon the side-plate, and the sheets and strips being slitted in and between their corrugations respectively.

3. In a device of the class described, a car-roof composed of sheets having perforated wings, and fasteners consisting of a body adapted to be secured to the side of a car and having a pin adapted to pass through the perforation in the wings and an arm on the body provided with an opening in its free end adapted to receive the pin.

4. In a device of the class described, a car-roof composed of sheets having perforated wings and perforated filler strips, and Y-shaped fasteners consisting of a 'body adapted to be secured to the side of a car and an arm adapted to receive the wings and filler-strips therebetween, an opening in the free end of theE arm, and a pin on the. body' adapted to pass through the perforations and into the opening in the arm.

5. In a device of the class described, a car-roof composed of a series of corrugated sheets having overlapping Wings, and a iillerstrip having a series of corrugations at one side adapted to register with andlill the corrugations of the sheets and its other side bent down under the wings to conform to the edge of the car.

In testimony whereof I aHiX my signature in presence of two witnesses.
